Abstract

The method is relatively simple and cheap. The names which are to be stored are spoken by a subscriber and converted by a vocoder (14) into digital signals. These are stored in a semiconductor memory (13). The subscriber keys in the telephone numbers associated with the names by means of a keypad (10), which in each case transfers the selected telephone number in digitised form to the semiconductor memory. By pressing a key (17), the subscriber can retrieve the stored names successively from the semiconductor memory and have them announced by the decoder (14). If the subscriber hears the required name, he prompts the semiconductor memory (13) to supply the telephone number associated with the name by pressing a further key (19). <IMAGE>

Description

Stand der TechnikState of the art

Die Erfindung geht von einem Verfahren nach der Gattung des Hauptanspruchs aus.The invention is based on a method according to the type of the main claim.

Es ist ein Fernsprechsystem bekannt, bei dem häufig benötigte mehrstellige Rufnummern mittels Kurzwahl gewählt werden. Dabei genügt beispielsweise die Wahl einer einzigen Ziffer der Ziffern 0 bis 9, um einen gewünschten Teilnehmer von zehn verschiedenen Teilnehmern zu rufen. Sollen jedoch zum Beispiel bis zu hundert Teilnehmer unterschieden werden, dann muß der rufende Teilnehmer bereits zwei Ziffern wählen, die er einem Verzeichnis entnehmen muß, in welchem die Namen der Teilnehmer und die zugehörigen Kurzwahl-Ziffern enthalten sind.A telephone system is known in which frequently required multi-digit numbers are dialed using speed dialing. For example, the selection of a single digit from the digits 0 to 9 is sufficient to call a desired subscriber from ten different subscribers. However, if, for example, up to a hundred subscribers are to be differentiated, the calling subscriber must already dial two digits, which he must take from a directory in which the names of the subscribers and the associated speed dial digits are contained.

Es ist weiterhin ein Wahlverfahren bekannt (Funkschau, 1986, Heft 15, Seite 48), bei dem nach einmaliger Speicherung von Namen und zugehörigen Rufnummern das Anrufen eines Teilnehmers dadurch ausgelöst wird, daß nur der Name des gewünschten Teilnehmers gesprochen zu werden braucht, wobei dann eine Spracherkennungsschaltung den gesprochenen Namen automatisch erkennt und das Aussenden der zugehörigen Rufnummer auslöst. Dieses Ver­fahren setzt jedoch einen hohen technischen und wirtschaftlichen Aufwand voraus.There is also a dialing method known (Funkschau, 1986, issue 15, page 48), in which, after the one-time storage of names and associated call numbers, the calling of a subscriber is triggered by the fact that only the name of the desired subscriber needs to be spoken, in which case a speech recognition circuit automatically recognizes the spoken name and triggers the transmission of the associated number. However, this process requires a high level of technical and economic effort.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Verfahren mit den kennzeichenden Merkmalen des Haupt­anspruchs hat den Vorteil, daß der technische und wirtschaftliche Aufwand zur Realisierung erheblich verringert werden kann, insbesondere dann, wenn der Vocoder die Sprachsignale auf eine verhältnismäßig geringe Datenmenge (zum Beispiel 2,4 kbit/s) reduziert.The method according to the invention with the characterizing features of the main claim has the advantage that the technical and economic outlay for implementation can be considerably reduced, in particular if the vocoder reduces the speech signals to a relatively small amount of data (for example 2.4 kbit / s) .

Durch die in den Unteransprüchen aufgeführten Maßnhmen sind vorteilhafte Weiterbildungen und Verbesserungen des in dem Hauptanspruch angegebenen Ver­fahrens möglich. Besonders vorteilhaft ist ein erfindungsgemäßes Verfahren, bei dem jeder als Digitalsignal gespeicherte Name nach dem Einspeichern in den Halbleiterspeicher automatisch oder durch Betätigen einer Taste über den Vocoder hörbar gemacht wird. Dadurch kann der Teilnehmer feststellen, ob der von ihm eingegebene und gespeicherte Name gut zu verstehen ist oder nicht. Reicht die Sprachverständlichkeit nicht aus, so wiederholt er die Eingabe des Namens noch einmal.The measures listed in the subclaims permit advantageous developments and improvements of the method specified in the main claim. A method according to the invention is particularly advantageous in which each name stored as a digital signal is made audible automatically after being stored in the semiconductor memory or by pressing a key via the vocoder. This enables the participant to determine whether the name they have entered and saved is easy to understand or not. If speech intelligibility is insufficient, he repeats entering the name again.

Zeichnungdrawing

Ein Ausführungsbeispiel zur Realisierung des erfindungsgemäßen Verfahrens ist in der Zeichnung anhand einer einzigen Figur dargestellt, die ein Block­schaltbild zeigt.An exemplary embodiment for implementing the method according to the invention is shown in the drawing with reference to a single figure, which shows a block diagram.

Beschreibung der ErfindungDescription of the invention

In der Figur bezeichnet 10 eine zum Beispiel zu einem Funktelefon gehörende Wahltastatur mit Tasten 11. Die Wahltastatur 10 steht mit einer elektroni­schen Steuerungsschaltung 12 in Verbindung, die wechselseitig mit einem Halb­leiterspeicher 13 und einem Vocoder 14 verbunden ist. Zu der Steuerungsschal­tung 12 gehören vorzugsweise fünf Tasten, das sind zum Beispiel eine Start­taste 15, eine Specichertaste 16, eine Abruftaste 17, eine Suchtaste 18 und eine Ruftaste 19. Der Vocoder 14 weist einen NF-Eingang 20 für ein Mikrofon 21 sowie einen NF-Ausgang 23 für einen Lautsprecher 24 auf. An einen Ausgang 25 des Halbleiterspeichers 13 schließt sich ein Wahlsignalgeber 26 an, der mit dem Modulationseingang des Sendeteils eines Funksende- und -empfangs­gerätes 27 in Verbindung steht. Dem Funktelefon ist vorzugsweise ein Anruf­beantworter 28 zugeordnet, der in dem Halbleitspeicher 13 gespeicherte Ansa­gen über den Vocoder 14 an das Funksende- und -empfangsgerät 27 weiterleitet und mit dem empfangene Sprachinformationen über den Vocoder 14 und die Steue­rungsschaltung 12 in den Halbleiterspeicher 13 übertragen werden. Zu diesem Zweck muß der Halbleiterspeicher 13 bezüglich seines verfügbaren Speicher­platzes derart bemessen sein, daß er nicht nur die Namen und Rufnummern der gewünschten Teilnehmer, sondern darüber hinaus die Informationen aus dem Anrufbeantworter-Betrieb speichern kann.In the figure, 10 denotes a dialing keypad with keys 11, which belongs, for example, to a radio telephone. The dialing keypad 10 is connected to an electronic control circuit 12, which is mutually connected to a semiconductor memory 13 and a vocoder 14. The control circuit 12 preferably includes five keys, for example a start key 15, a specifier key 16, a call key 17, a search key 18 and a call key 19. The vocoder 14 has an LF input 20 for a microphone 21 and an LF- Output 23 for a speaker 24. An output signal 25 of the semiconductor memory 13 is followed by a selection signal transmitter 26 which is connected to the modulation input of the transmission part of a radio transmitter and receiver 27. The radio telephone is preferably assigned an answering machine 28 which forwards announcements stored in the semiconductor memory 13 to the radio transceiver 27 via the vocoder 14 and with which received voice information is transmitted via the vocoder 14 and the control circuit 12 to the semiconductor memory 13. For this purpose, the semiconductor memory 13 must be dimensioned with respect to its available storage space in such a way that it can store not only the names and telephone numbers of the desired subscribers, but also the information from the answering machine mode.

Die vorstehend beschriebene Vorrichtung hat folgende Funktion.The device described above has the following function.

Zunächst muß der Funkteilnehmer die für ihn wichtigen Teilnehmer mit Namen und Rufnummern speichern. Hierzu spricht er nach Betätigung der ersten Taste 15 (Starttaste) den ersten Namen in das Mikrofon 21. Der Name wird durch den vocoder 14 digitalisiert und nach Betätigung der zweiten Taste 16 (Speicher­taste) in dem Halbleiterspeicher 13 abgelegt. Anschließend kann der in dem Halbleiterspeicher gespeicherte Name entweder automatisch oder nach Betäti­gung einer dritten Taste 17 (Abruftaste) über den Vocoder 14 mit dem Laut­sprecher 24 hörbar gemacht werden. Nur in dem Fall, daß der wiedergegebene Name schwer verständlich ist, wird der Teilnehmer das Einspeichern des Names wiederholen.First, the radio subscriber must save the subscribers important to him with names and phone numbers. For this purpose, he speaks the first name into the microphone 21 after actuating the first key 15 (start key). The name is digitized by the vocoder 14 and stored in the semiconductor memory 13 after actuation of the second key 16 (memory key). The name stored in the semiconductor memory can then be made audible either automatically or after actuation of a third key 17 (call key) via the vocoder 14 with the loudspeaker 24. Only in the event that the reproduced name is difficult to understand, will the participant repeat the saving of the name.

Ist der erste Name richtig gespeichert, dann gibt der Teilnehmer die zu dem Namen gehörende Rufnummer durch Betätigen der entsprechenden Tasten 11 in die Wahltastatur 10 ein, und die einzelnen Ziffern der Rufnummern werden nach Betätigen der zweiten Taste 16 (Speichertaste) in digitaler Form ebenfalls in dem Halbleiterspeicher 13 gespeichert. Das Speichern von Name und Rufnummer wird vorzugsweise durch eine von der Steuerungsschaltung 12 bereitgestellte Platznummer ergänzt, die ein eventuell später notwendig werdendes Umsortieren von Namen und Rufnummern vereinfacht und gegebenefalls eine Prioritätenver­teilung zuläßt; zum Beispiel Teilnehmer 1 ... 10 = sehr wichtige, 11 ... 20 = wichtige, 20 und ff. = weniger wichtige Teilnehmer. Anschließend speichert der Teilnehmer nacheinander den zweiten bis n-ten Namen mit jeweils zugehöri­ger Rufnummer in analoger Weise in den Halbleiterspeicher 13 ein. Sind dann in dem Halbleiterspeicher alle gewünschten Teilnehmernamen und -rufnummern gespeichert, so steht dem Funkteilnehmer ein akustisches Teilnehmerverzeich­nis zur Verfügung, das er durch Betätigen der vierten Taste 18 (Suchtaste) "durchblättern" kann. Dabei wird vorzugsweise dafür gesort, daß das Durch­blättern wahlweise vorwärts oder rückwärts sowie mit unterschiedlicher Geschwindigkeit erfolgen kann. Hierzu sind unter Umständen weitere Tasten erforderlich. Die Maßnahmen für das Durchblättern des akustischen Teilnehmer­verzeichnisses sind dem Fachmann aus der Technik der Digitaluhren geläufig. Hat der Teilnehmer beim Abrufen des Teilnehmerverzeichnisses den gewünschten Teilnehmernamen im Lautsprecher 24 gehört, dann läßt er die vierte Taste 18 los. Betätigt er dann die fünfte Taste 19 (Ruftaste), so veranlaßt die Steu­erungsschaltung 12, daß der Halbleiterspeicher 13 die zu dem Namen gehörende digitalisierte Rufnummer an dem Ausgang 25 abgibt. Der mit dem Ausgang 25 verbundene Wahlsignalgeber 26 erzeugt aus der digitalen Rufnummer ein Ruf­signal entsprechend dem in dem Funktelefonsystem vorgesehenen Rufverfahren und leitet das Rufsignal an den Sendeteil des Funksende- und -empfangsgerätes 27 weiter.If the first name is saved correctly, the subscriber enters the number belonging to the name into the dialing keypad 10 by pressing the corresponding keys 11, and the individual digits of the numbers are also digitally activated after pressing the second key 16 (memory key) the semiconductor memory 13 stored. The storage of name and phone number is preferably supplemented by a location number provided by the control circuit 12, which simplifies any re-sorting of names and phone numbers that may become necessary later and, if necessary, permits priority distribution; for example participants 1 ... 10 = very important, 11 ... 20 = important, 20 and ff. = less important participants. The subscriber then stores the second to nth names, each with the associated call number, in an analogous manner in the semiconductor memory 13. If all desired subscriber names and call numbers are then stored in the semiconductor memory, the radio subscriber has an acoustic subscriber directory available which he can "browse" by pressing the fourth key 18 (search key). In this case, preference is given to the fact that the leafing through can take place either forwards or backwards and at different speeds. Additional buttons may be required for this. The measures for leafing through the acoustic subscriber directory are familiar to the person skilled in the art from the technology of digital clocks. If the subscriber has heard the desired subscriber name in the loudspeaker 24 when calling up the subscriber directory, then he releases the fourth button 18. If he then presses the fifth key 19 (call key), the control circuit 12 causes the semiconductor memory 13 to belong to the name delivers digitized phone number at the output 25. The dialing signal transmitter 26 connected to the output 25 generates a call signal from the digital call number in accordance with the call method provided in the radio telephone system and forwards the call signal to the transmitting part of the radio transceiver 27.

In dem vorstehend beschriebenen Ausführungsbeispiel sind die Tasten 15 bis 19 zusätzliche Tasten zu der Wähltastatur 10. Die Funktionen der Tasten 15 bis 19 können gegebenenfalls die Tasten 11 durch Doppeltbelegung übernehmen.In the exemplary embodiment described above, the keys 15 to 19 are additional keys to the dialing keyboard 10. The functions of the keys 15 to 19 can, if necessary, take over the keys 11 by double assignment.

Als Vocoder 14 eignet sich beispielsweise ein LPC-Vocoder mit einer Bitrate von 2,4 kbit/s und als Halbleiterspeicher eine E²PROM-Schaltung.For example, an LPC vocoder with a bit rate of 2.4 kbit / s is suitable as vocoder 14 and an E²PROM circuit as semiconductor memory.
